Villarrica volcano (Chile): small lava lake in summit crater confirmed

Magma has reached the surface of the inner summit crater. Strombolian activity has formed a new small cone containing a small lava lake in its open vent. This followed a strong increase in volcanic tremor to about 20 times background level starting since Thursday. Glow from the volcano's top has become visible at night.
An overflight confirmed the presence of lava inside the deep pit at the summit crater. SERNAGEOMIN raised the alert level of the volcano to yellow.
So far, this activity represents a very typical state of the volcano. If it remains like this, it does not pose significant threats to the surroundings unless activity strongly increases, which could result in the generation of lahars (mud flows due to meltwater from the summit) in particular. These could threaten the areas of the towns of Villarrica, Pucón, Curarrehue and Panguipulli. Chile's civil protection ONEMI has issued a pre-alert, still coded as green, as a precaution.
from Smithsonian / USGS Weekly Volcanic Activity Report 4-10 February 2015:
Projecto Observación Visual Volcán Villarrica (POVI) reported that at night during 4-5 February faint incandescence was detected with a near-infrared camera. On 5 February Strombolian explosions ejected tephra several hundred meters high.
On 6 February tephra was ejected about 65 m above the crater rim and two consecutive ash emissions were observed. OVDAS-SERNAGEOMIN reported that the Alert Level for Villarrica was raised to Yellow (the second lowest level on a four-color scale) due to the increased seismicity, indicating a fluctuating lava lake and small explosions. Scientists noted a rise in the lava-lake level during an overflight.
POVI reported that on the morning of 7 February bombs were ejected from the crater, some almost 5 m in diameter. Later that day the intensity of the explosions decreased and crater incandescence became irregular.

Increasing activity at the volcano was reported by the Projecto Observación Visual Volcán Villarrica (POVI), suggesting that deep-seated strombolian activity has resumed in the summit crater. ... [mehr]

According to Projecto Observación Visual Volcán Villarrica (POVI), satellite images of Villarrica acquired on 25 July revealed a weak thermal anomaly. On 29 July observers photographed the crater and described a thermal anomaly on the S edge of the crater rim, in the same area from which a lava flow originated on 29 December 1971. They also heard deep degassing sounds. A second photograph showed a diffuse gas plume rising from the bottom of the crater, and ash and lapilli on the snow on the inner crater walls. ... [mehr]

Terrestrial and satellite observations confirm that for about 2 weeks weak explosive activity deep within the summit crater has resumed and indicates that magma might have begun to rise again within the volcano. ... [mehr]

Incandescence from Villarrica's crater had subsided mid-April 2012 and was undetected by satellite and ground observations at least through 10 November. Images captured by a camera in Pucon (16 km N) on 10 November showed an increase in the plume intensity. Small water vapor plumes, 50 m wide, rose from the depths of the crater. [mehr]

In its activity report published on 1 May, SERNAGEOMIN reported low levels of seismicity during April 2012 from Villarrica volcano and has it currently at GREEN level. Glow from the summit was visible most of the month. [mehr]
